Standardized by the DEA, ATF, and FBI SWAT team, the Model 552 holographic weapon sight is the sight of choice for such military units as the Stryker Brigade, 10th Mountain, and 3rd Infantry. The Model 552 sports a revolutionary sighting system based on advanced holographic technology. The design works by using laser light to illuminate a holographic pattern embedded in the heads-up display window. When the shooter looks through the window, he or she will see a virtual red image of a reticle pattern projected onto the target plane. Overall, the holographic sight improves target acquisition, boosts accuracy, and increases control over the shooting environment.

The Model 552 is built to last, with a rugged aluminum hood assembly and knobbed, tool-free mounting bolt. The battle-proven design can withstand the abuse that any harsh environment, high-powered weapon platform, or military mission can dish out. Other features include a 65 MOA ring reticle with a 1 MOA aiming dot; support for two 1.5-volt AA batteries (lithium or alkaline); unlimited eye relief; and 30 brightness settings. The Model 552 is compatible with Gen I-IV night vision systems and mounts on 1-inch Picatinny or Weaver rails.
